transform a unit cube to view frustum?

i want to create a shape, that shows the camera view frustum of a specific camera. my*question: is there a simplier way, than create a shape (SoTriangleStripSet) to see the viewfrustum? so i didn't no that way, i created a unit cube (sidelength 2 ; center=(0,0,0) ) with a triangle strip set and want to transform it to a view frustum.

Working on a robot simulator and need a fast way to determine whether two unit cubes, that have been arbitrarily rotated, scaled and translated but not twisted or sheared, intersect. Do not need to kn?ow anything about the shape of the intersection just whether it occurs.
